Dutch chemial DSM-daughter Dyneema starts a patent case against Chinese Hangzhou Pivot. According to DSM Hangzhou Pivot is infringing its Dyneema-fibre patent, used for armouring cockpit doors. DSM asks the Paris Court to order an injunction of the sale of fibre and rope by Hangzhou and a recall of all sold materials. Besides, DSM demands compensation damages.
During the state security exhibition Milipol 2005 in Paris, DSM took possession of the materials of Hangzhou Pivot, because they allegedly infringed DSM's patent.
